1 Claim.

This invention relates to improvements in metal windows and screens.

An object of the invention is to provide an improved construction wherein vertically extending metal sash guides are supported at the opposite sides of a window frame to guide and support the window sashes formed with spaced glass panes.

Another object of the invention is to provide an improved window construction wherein the Window sash will be formed with spaced double glass panes, said sash being slidably received in metal sash guides secured to the opposite sides of the window frame and engaged along the edges by spring arms secured to the inner surface of said sash guides.

A further object of theinvention is to provide an improved window construction wherein sash guides will be secured to the opposite sides of a window frame, together with sashes slidably supported therein, having their adjacent cross members at the bottom of the top sash and at the top of the bottom sash transversely rabbeted to form a weatherproof interlocking joint when said sashes are in closed position.

Another object of the invention is to provide an improved window construction wherein sash guides will be supported at the opposite sides of a window frame, together with resiliently mounted slidable sashes having either single or double glass panes, whereby the sashes will be resiliently supported when opened to any position within the limits of adjustability, and when both sashes are disposed in the upper portion of the window frame, a detachable screen may be resiliently supported in the lower portions of the sash guides.

Another object of the invention is to provide an improved window construction which will be highly efficient in operation and relatively inexpensive to manufacture and produce.

Other objects will appear as the description proceeds.

, Like characters of reference are used throughout the following specification and the accompanying drawings to designate corresponding parts.

In carrying out the invention, there is provided a window frame generally denoted by the reference numeral l including oppositely disposed side frame members 2 and 3.

By referring to Figure 2 of the drawings, there is shown a window construction having opposite side frame members 2 and 3, and a pair of outside metal sash. guides 4 and 5 which are U-shape in cross section and are secured to the opposite faces of said frame members 2 and 3 by the screws 6. The inside sash guides l and 8 for the'lower sash, are rabbeted out to form thespaced seats. 9 and I!) in which the sash Y frames supporting the spaced panes of glass II and 12 are adapted to-be received. Locking strips I3 and I4 will be secured about the edges of the glass panes II and l2 to hold the same in position within the sash frame 1.

In Figure 5 of the drawings there is illustrated the oppositely extending spring arms I 5 and I6 which will be secured by the rivets I! to the inner surface of the outermetal sash guides 4 and 5, and will resiliently engage the adjacent outer edges of the inner metal sash guides 7 and 8 to support the same in any degree of open position.

The internally threaded nut members l8 will be secured to the outer surface of the outer metal sash guides 4 and 5 and will receive the adjusting and control threaded bolts [9 which extend through the inner metal sash guides l and 8; to

support the coil tensioning springs 20 disposed about them in contact with the adjacent surfaces of the said inner-and outer metal sashguides. The heads of the bolts I9 are received in the recesses or bores 2| formed in the inner metal sash guides. W Breather openings 22 will be formed'at the lower end of the inner metal sash guides so that expanding air between the glass panes may escape when heated by the sun shining on the glass panes.

In Figure 3 of the drawings, there is illustrated the use of an outer metal sash guide 24 at the top of the upper sash 25, and a lower sash 26 having a Weatherstrip 2'! formed transversely of its lower member. Single panes of glass 28 and 29 will be secured by the locking strips 30 in the sash frame 25 and 26. 3| will be adjustably and slidably received in the, outer sash guide 24. The upper cross member 32 of the sash 26 and the adjacent lower cross member 33 of the sash 25 are rabbeted to provide the cooperating interlocking V-shape tongues 34 and V-shape grooves 35 for completely Weatherstripping the middle of the window.

' In Figure 6 of the drawings, there is illustrated an outer double metal sash guide 36 which is U- shape in cross section and secured to the opposite faces of a window frame 31 by means of the screws 38, said guides extending the full length of the window frame 31. An inner double metal sash guide 39 is formed with the space guide flanges 40 and 4|, and 42 and 43, respectively, in which the double sash frames 44 and 45 are adapted to slide. The sash frames 44 and 45 are adapted to receive the spaced glass frames 46 and.

41, and 48 and 49, respectively, and to be'held in place by means of the locking strips 50 and 51. Of course, breather openings (not shown). will also be provided for the equalizing of the expanded air when the glass panes are heated by the sun shining upon them. Adjusting bolts 52 will be positioned in the bores 53 in the inner metal sash guide 39 and will extend therethrough and through the outer metal sash guide 36 to be received in the internally threaded nuts 54 attached to the guides 36.

In Figures 7. and 8 there is illustrateda resiliently tensioned screen and a method of supporting the same upon a window. A U-shape guide channel 55 is slotted in its upper and lower ends as at 56, and cooperates with the pins or bolts 51 extending into the screen frame 58 to limit the movement thereof. The wire screen 59 will be held in place by the offset. clamping strips 68 which are fastened to said frame 58by means of the screws 6|, as best shown in Figure 7 of the drawings. oppositely. disposed U-shaped side adjusting channels 62 are supported within the guide channel 55 and overlie the opposite side edges of the screen frame 58. A plurality of laterally extending coil springs 63 are secured by means of the screws64 to the "opposite side edges the side of the window, orfrom a sash guideif the screen has been placed therein.

In Figures'Q, and '11, there is shown a metal grip guide construction which, is formedof the U'-shape metal guide strips 65, the central portion 66, of which is inwardly bowed and attached:

10 An inner metal sash guide to the side edges of thewindow frame 61 by means of the strips 68 and screws 69, which serve to. i

make the opposite sides 'l0 of the guide grips more firmly on a sash or plate of glass as the.

screws 69 are tightened' down on the bowedcentra l section. Slidable strips ll will be positioned.

posed ov r" the screws 13 ,extending loosely.

through said strip H and through the strips 68 at the central portion 66 of said guide strips 65. Upstanding collars 14 will be formed on the strip H to protect the heads of the screws 13. A window or screen sash or glass pane (not shown) will be supported between the metal strip guides and may be removed from the outside by pushing the window. or screen sash or the glass pane toward oneside against the action of the springs 12, thereby releasing the same from said guides. The side 10 of the grip guide will be bent upon itself for reinforcing the same, and if desired may support a strip of weatherproof felt (not shown).

From the foregoing description it will be apparent that there has been provided a highly efficient form of metal window and screen construction.

While the preferred embodiment of the instant invention has been illustrated and de-,

scribed, it will be understood that it is not intended to limit the scope of the invention thereto, as many minor changes in detail of construction may be resorted to without departure from the spirit of the invention.

Having thus described my invention what I tensioning means between said outer and inner guides, and adjusting means between'said outer and inner guides for variablytensioning'said re silient tensioning mean's said tensioning means including divergentspring arms disposed between said inner and outer guides, the 'ends of said arms proxi'mateto each other being secured to said outer guide and the opposite ends ineluding laterally extending wings bearing against said inner guide, a threaded socket in said outer guide and window frame between the proximatev ends of said arms, a headed bolt having a thread.

ed end received in said socket and extending between and through saidinner and outer guides,

the headed portion of said bolt extending through said inner guide, and a coil spring wound about said.bolt andinterposed' between said inner and outer. guides.
